How accurate is Birdsong's bird identifier?

It runs Google's Perch, a research-grade acoustic model covering nearly 15,000 species. When a call is ambiguous, we say so honestly and let you record a second clip to confirm, rather than guessing.

Is my recording stored?

No. Your audio is used to identify the bird in the moment and isn't saved to our servers. The birds you confirm are kept as cards in your own field journal; the recordings themselves are not.

Is the bird identifier free?

Yes — identify birds every day for free, no account required. Birdsong Pro ($3.99/mo or $39.99/yr) unlocks unlimited IDs, full field guides, your growing collection, and shareable Field Report cards.

Do I need an account or internet to identify a bird?

You'll need a connection to identify, since the AI runs in the cloud. No account is needed to try it — sign in with Google or email to save your field journal and sync it across devices.

Field notes

It is strictly endemic to the Magdalena Valley and Chicamocha River systems in Colombia.
The species is highly specialized to xerophytic scrub and dry forest environments which are under pressure from agricultural expansion.
Its plumage features a bronzy-green crown and back contrasted against a deep, uniform chestnut-colored belly.
It primarily feeds on the nectar of flowering cacti, Agave, and various native shrubs like those in the Ericaceae family.
Though once feared near extinction, recent surveys in the Chicamocha canyon have identified more stable population clusters.

Habitat

Arid xerophytic scrub, dry canyons, and semi-open woodland slopes between 850 and 2,200 meters.

Range

Eastern Andes of Colombia, specifically within the Santander and Boyacá departments.
